The Performance of Commercial pH-Sensitive Ion-Selective Field Effect Transistors.

ABSTRACT: pH-sensitive ion-selective field effect transistors (ISFETs) are commercially available nowadays, offering high robustness, resolution, accuracy, and durability. A crucial drawback is their high price and permanent power demand. Incorporating commercially available small-sized ISFET sensors into battery-powered devices requires a thorough evaluation and the development of strategies to reduce power consumption. In this work, a direct comparison of three different commercial ISFETs is presented using a newly developed evaluation process that aims to investigate long-term performance. The different behaviors in conditioning, linearity, accuracy, response times, and long-term stability in detail are discussed. Furthermore, strategies to decrease power consumption are presented by adjusting th
